Pressure compensation element for M 40 knockouts
For the reduction of condensation by pressure compensation in power distribution systems
ISO thread M 40 x 1.5
Bore-hole: Ø 40.3 mm
Wall thickness of up to 8 mm
With counter nut
For indoor (normal environment and/or protected outdoor) and outdoor installation (harsh environment and/or outdoor)
Ambient temperature – 25 °C to + 55 °C
In order not to exceed leakage limit of 0.07 bar with pressure compensation, one pressure compensation element BM 40G must be used per 122 liters (122000 cm³) of enclosure volume.
Example: enclosure size 60 cm x 60 cm x 17 cm = 61200 cm³ = 61,2 litres. Number of necessary BM 40G (M40) = 1 piece.
